Formula and explanation
In a balanced chemical equation, the ratio of the stoichiometric coefficients (coefficients) of the substances equals the ratio of their amounts of substance. Formula: For the reaction aA + bB ightarrow cC + dD, we have (n A)/(a) = (n B)/(b) = (n C)/(c) = (n D)/(d) Applicable conditions: Balanced chemical equations. Explanation: This is the core relationship for quantitative calculations based on chemical equations.
